Description

[Detailed description of the invention] This invention can promote germination by pushing seeds sown in the field at the trench position into the soil using a seed pusher, without causing the seeds to float or be blown away by the wind. This invention relates to a seeding device in a direct seeding machine.

A seeding pipe is installed in an open shape on a sliding body that can slide along the field surface, and a trench cutting blade is installed on the back of the sliding body in front of the mounting position of the seeding pipe, and a soil cover plate is installed on the back side of the sliding body. A sowing device for a direct sowing machine is well known, in which the seeds are placed in the field at the position of the trench and the seeds are buried to an appropriate depth by covering the soil.

By the way, if the seeds sown in the trench position are simply covered with soil as described above, the seeds are simply sown in the field area at the trench location, so when the field is flooded, Some of the seeds become floating, causing a floating root phenomenon, and when the field is dry, they are blown away by the wind, resulting in disadvantages such as the inability to germinate and grow in the correct location.
This was strongly desired to be improved.

In view of the above, the present invention is designed to immediately push the seeds sown on the field surface at the groove position plasticized by the groove cutting blade into the soil using the seed pusher and bury them, even if the field is flooded. To provide a sowing device for a direct sowing machine that reliably prevents seeds from floating or being blown away even when the seed is planted, and allows all seeds to germinate and grow accurately at the planting position. The configuration of the device of the present invention will be described below with reference to a preferred embodiment shown in the accompanying drawings.

Reference numeral 1 denotes a sliding body that can freely slide along the field A, and in this example, the entire body is molded into a boat-shaped flat plate, but the inside is hollow. It may also be a float-like sliding body.

A mounting bracket 2 whose upper and lower ends are open is installed approximately at the center of the sliding body 1.
A seeding tube 3 having an open bottom is inserted into the tube and fitted therein.

Depending on the mounting position of the seeding tube 3, there is a groove cutting blade 4 on the back surface of the sliding body 1 at the front, which has a sharp tip and is generally boat-shaped when viewed from the side. The seed pusher 5 is generally boat-shaped when viewed from the side, has a flat surface 6 at the bottom, and has a width approximately equal to the width of the groove cutting blade 4.
Seeds C sown on the field area B at the groove position formed by the groove cutting blade 4 are reliably pushed into the soil by the seed pusher 5, thereby eliminating the phenomenon of floating or blown away seeds. Get used to it.

Therefore, in order to perform the above-mentioned furrowing, sowing, and pushing operations continuously and consistently, the furrowing blade 4, seeding pipe 3, and seed pushing body 5 are arranged in series along the traveling direction of the sliding body 1. has been done.

Reference numeral 7 denotes a towing fitting for moving the sliding body 1 along the field scene A, and the towing fitting 7 is normally attachable and detachable to the rear of a mobile agricultural machine (not shown) equipped with a prime mover, running wheels, a handle, etc. They are connected as follows.

Next, the operation of the present invention will be explained.

If you want to use the combing device to reliably push the seeds into the soil at the trench cutting position, first connect the traction fitting 7 to a suitable mobile agricultural machine and move the sliding body 1 in the direction of the arrow toward the field scene A. Slide along.

Then, as the sliding body 1 advances, a groove of an appropriate depth is excavated in the field area A, and seeds are sown from the sowing tube 3 on the field area B at the groove-cutting position.

However, the groove cutting blade 4 is located immediately behind the seeding pipe 3.
Since the seed pusher 5 is positioned to advance along the groove made of plastic, the seeds C are pushed into the soil by the flat surface 6 of the seed pusher 5 and buried.

As a result, even when the field is flooded, there is no floating root phenomenon that occurs when some of the seeds rise to the surface of the water, or the phenomenon where some of the seeds are blown away when the field is dry. It is possible to germinate and grow by finishing the sowing work in the correct position.

In short, in the present invention, a seeding tube 3 is attached in an open manner to a sliding body 1 that can slide along a field area A, and a groove cutting blade 4 is provided on the back surface of the sliding body 1 in front of the attachment position of the seeding tube 3. of,
Further, on the rear back side, there are provided seed pushers 5 each having a generally boat-shaped overall shape when viewed from the side, a flat bottom, and a width approximately equal to the width of the groove cutting blade. At the same time, since the groove cutting blade 4, seeding tube 3 and seed pushing body 5 are arranged in series along the traveling direction of the sliding body 1, sowing can be carried out in the field area B at the groove cutting position excavated and formed by the groove cutting blade 4. All of the crushed seeds C are immediately forcibly pushed into the soil by the seed pusher 5 and buried, and even when the field is flooded, there is a phenomenon in which the seeds float, and even when the field is dry, there is a phenomenon in which the seeds C are forced into the soil and buried. Not only can this eliminate the phenomenon of seeds being blown away by water, allowing the sowing to be carried out in precise locations, resulting in more efficient germination and growth, but Seed C can be planted shallowly in low-temperature regions. It has an effect that is optimal as a seeding device.
